A MOTOR-DRIVEN GRASS MOWER

A motor-driven grass mower is provided to reduce fatigue of workers even in working with lifting a rotary cutter up, by keeping the weight balance well by installing a motor unit in the middle. A motor-driven grass mower(1) is composed of an operating unit(3) equipped with a grass cutter, a linear cutter, or an attachment for agriculture; a motor containing unit(6); a power unit(8) storing a battery(7); and front and rear operating sticks(10,11). The operating unit is installed at the front end of the grass mower. The motor unit is installed in the middle. The front operating stick is disposed between the operating unit and the motor unit. The power unit is mounted at the rear side of the grass mower. The rear operating stick is disposed between the motor unit and the power unit. A conductive member is embedded in or installed at the rear operating stick to supply power to a motor. A power transmitting member is embedded in the front operating stick to transmit power of the motor to the operating unit.
